But the 25-year-old Romanian saved her best tennis to turn the match around for a straight sets victory.

"It was a good match. I think I played really well the whole match, even if she has the 5-3 in the second set," Halep said afterward. "I felt that I was pushing her back, and also I was rolling the ball pretty well. I think it was a very high standard of tennis today. Also, she played really well. I mean, she's a very tough opponent when I play her always.

Halep will next play No. 21 seed Carla Suarez-Navarro of Spain, who was a 6-4, 6-4 winner over 14th-seeded Elena Vesnina of Russia.

Former top-ranked Caroline Wozniacki of Denmark advanced to the to the fourth round, beating American teenager CiCi Bellis 6-2, 2-6, 6-3 when their match resumed after being suspended due to darkness on Friday.
